[Freesurfer] mapping an set of talairach points

I'm still trying to figure out a way to display an ROI made elsewhere on my freesurfer data. I can get all ROI I need in freesurfer in talairach points (ie. a list of talairach points that cover the entirety of the ROI space), but as far as I can see, I can only load one talairach point at a time (using select_talairach_point), and then the last point is lost with each subsequent call.

What I really want to do is select a region on the surface that covers a set of talairach coordinates (instead of say, dilating from 1 talairach point). Is there any way to do this? Should I use something like the talairach transform file to change it into surface coordinates and load those like a label somehow, or is there some other way?
